Abstract: A process for writing with updating and reading informations on a non-erasable support organized in sector form. Each sector comprises a synchronization field, a data field, a length field, a type field, an address field and a redundancy field. The data information to be stored and its length are respectively written into the data and length fields. The value written into the type field indicates whether the data information can be updated or not. If updating is possible, the address field receives a pointer designating the free sector of the support, so that said sector is reserved for a possible updating. If updating is not possible, a predetermined value is written in the address field. The error correcting code written in the redundancy field takes account of the contents of the data, length, type and address fields. Writing in all the fields of a sector takes place in a single writing operation.

Abstract: A distribution class surge arrester comprises a core formed of distributed zinc oxide varistor blocks, aluminium blocks acting as heat sinks and as spacers providing voltage grading and required arcing distances, and terminal blocks held in face to face contact by means of a glass reinforced epoxy shell which is formed by winding a pre-preg onto the assembled blocks and thermally curing under mould pressure within an evacuated mould. The core is housed within a polymeric shedded housing which is formed by shrinking a heat-shrink shedded sleeve onto the core with a sealant provided in the interface of the core and the sleeve, and end caps are sealed to the ends of the structure thus formed. The all solid-state arrester thus formed has performance and cost advantages over conventional porcelain housed arresters and furthermore has very considerable physical strength enabling it to serve additionally as a stand-off support insulator in situations where con­ventionally separate arrester and support insulators were required.

Abstract: A pump is provided within a vortex generator having a plurality of equally spaced blades which rotate in a pump casing to form a nucleus of fluid in the shape of an ellipsoid having an upper tapered end and a lower tapered end with a thicker central section at the blades. Fluid flows in a synchronized flow from the lowered tapered end of the nucleus in a rotating vortex column of fluid which initially flows out of the pump inlet to swirl the ambient fluid about the inlet and causes a low pressure area and a swirling of the ambient fluid to flow inwardly through the pump inlet in a direction counter to the vortex column flow. A belt of fluid rotates between the nucleus and the pump casing. The blades are curved to retain fluid in the nucleus and momentum energy is cumulatively applied to keep the swirling column of fluid swirling through the pump outlet. A tapered section on the pump between the pump inlet and pump outlet assists in flow therebetween. A divider may be provided in the pump casing with an opening in the divider to allow the vortex column to flow from a vortex generating chamber to a pump discharge chamber while debris hits the divider and is prevented from flowing into contact with the blades. Pressure boosters may be added to the blades.

Abstract: A support assembly is provided which is intended to be capable of use particularly for supporting equipment used in medical technology. Such support assemblies are subject to the problem that sensitive supply lines must be guided through the parts of the support assembly which can move relative to one another. The design of the supporting assembly is complicated to avoid damaging these lines. Furthermore, springs and, if necessary, a brake are provided to compensate for weights. In order that the supply lines are guided in a protected manner and, at the same time, that the compensating springs and, if required, brake, are easily accessible from the outside as replaceable parts, the support assembly has a hollow space for carrying the supply lines and a compression spring for mass compensation. One bearing for the compression spring is connected to the outside of the support assembly arm and the other is connected to the moving part, such that the spring is arranged outside the hollow space. <IMAGE>

Abstract: Method and circuitry is disclosed for controlling and stabilizing temperature of a resistance heat sealing element used in packaging operations. Temperature of the heat sealing element is measured by monitoring its resistance by means of a current sensing resistor placed in series with the heat sealing element. The resistivity of the heat sealing element is a function of temperature and current measurement, assuming substantially constant applied voltage, is an accurate measure of sealing element temperature. The circuitry reduces application of electric power to the sealing element in response to current in the sealing element dropping below a predetermined level. The circuit either continues application of electric power, or increases it, in response to the current being above the predetermined level. Circuitry is also provided for compensating for undesirable line voltage changes to maintain the heating element at a constant temperature. Means is provided for adjusting the predetermined temperature at which power cut off occurs. The circuit and sealing element can be operated in either a continuous manner of in a "one-shot" fashion which has been determined as particularly useful for making seals which bear embossed indicia.

Abstract: Homogeneous free-flowing prods. such as emulsions or creams are obtained when the contents of a bowl are forced radially outwards through holes in a stator surrounding a bladed central rotor driven in gyroscopic manner by an electric motor. The feed faces of the baldes are so shaped that in one rotationdirection the prod. meets the hole walls substantially at right angles.  In the opposite rotation direction, esp. after change by electrical switching, flow is directed towards the holes, with optimum pumping effect.  The blades leave two main surfaces contributing to this double effect, viz a radial surface for homogenising, and a spiral surface with constantly changing distance from the stator for the pump effect.  The two faces are mutually perpendicular.  The stator may also be bladed.

Abstract: Disclosed is a mode field modifier (40) for use with an optical fibre (54) having a core (56) and a cladding (58) of outside diameter d. The modifier comprises a modifier core (42) having a refractive index n1. Surrounding the modifier core is first cladding layer (44) having a refractive index n2 that is less than n1. On the surface of the first cladding layer is a second cladding layer (46) having a refractive index n3 which is less than n2. The modifier is tapered intermediate its ends whereby it has a large diameter end and a small diameter end. The diameters of at least the core and first cladding layer at the large diameter end are greater than the corresponding diameters at the small diameter end. The diameter D1 of the first cladding layer at the large diameter end is greater than d. An axially disposed hole (52) in the large diameter end receives a fiber (54) which is held in such alignment with the mode field modifier (40) that it is in light coupling relationship with the modifier core (42). The mode field of a signal coupled from the fiber to the mode field modifier expands as it propagates through the tapered portion of the modifier to the small diameter end. An in-line coupler between two optical fibers is effected by connecting together in axial alignment two such mode field modifiers with their small diameter ends adjacent one another.
